Aharonov and Bohm argue for locality by noting that “according to our current relativistic notions, all fields must interact only locally [1]}." As their paper pre-dates Bell's formulation of locality, and they do not explicate what they mean by locality, it is not clear if Aharonov and Bohm have something like local beables in mind. It is not even clear if they have signal locality in mind, although they can certainly be read that way. At the very least, their notion of locality seems more in line with the idea that a theory is local when given in terms of equations of motion where the interactions only take place when the coordinates of the interacting systems coincide. Call this local interactions.
